I am using hptuners on my 2018 sport CC. I had to send my PCM off for them to unlock which took a full week including shipping time. If you do over night shipping expect it to take roughly 4-5 days to get it back.
So far I am happy with the tuner itself and is IMO user friendly.
Awesome! You have no idea, I went through the headache of installing the Security access cable and HP's instructions are not very helpful. When you remove your radio you will see a bracket bolted with 3 7mm bolts behind the radio. The Security gateway is attached to that bracket. I had to unbolt it to unplug mine to plug in the access cable.
Yup I do!!! plenty of scratched up hands getting that sucker in there.
Did that on Friday - instructions suck and its definitely not very obvious. I had a big helping hand from one of the guys on FB Ram Performance group who has also done it... so his guidance made all the difference.
Just to give you a little insight to where I am at on my 18 sport. I'm running with a custom tune, 180 tstat and electric fan only I'm putting out consistent 14.40s in the 1/4 at 95 mph in 2800 DA with 110-120 IAT. Which dropped me from 14.8s in slightly better DA at 93 mph. I'll be looking for high 13s in the next 2 weeks once the headers and intake are installed.
